Hi, i have solved the problem, but i don't know how, what i did was simply open a previous version of my project to see if it worked, and it did, i think maybe my last project file got corrupted due to the upgrade of Construct 2, i really don't have an answer.
By the way if anyone of you guys want to do the array storage here is the tutorial i followed, it's a bit long, but it's totally worth it, as i can't post the url of the video, just look up in youtube for the channel ArcadEdGames and there must be a video with the title Construct 2 Tutorial - Top 10 High Score
